The plot centers around young Jay Gardiner, who travels to the coast of Central California after his father's death to fulfill his last wish. However, a routine dive into the ocean unexpectedly turns into a deadly struggle. Underwater, Jay finds himself next to a giant sperm whale and ends up inside the massive creature. Escaping such a trap seems nearly impossible, and the hero's situation is further complicated by another factor: he has about an hour's worth of oxygen left. Now every minute counts. Cut off from the outside world, Jay must find a way out on his own. Surprisingly, the key to his salvation becomes the knowledge and life lessons that his father once passed on to him. The creators of the film promise that 'Whalefall' will not only be a tense survival thriller. Behind the extreme story lies a family drama about the relationship between a father and son, the loss of a loved one, and the hero's attempt to come to terms with his own past. The film is based on the novel of the same name by American writer Daniel Kraus. The director's chair is taken by Brian Duffield, known for the sci-fi thriller 'No One Will Save You.' Kraus and Duffield worked together on the screenplay adaptation. The main character is played by Austin Abrams, familiar to audiences from the series 'Euphoria' and the film 'The Weapon.' His father is portrayed by Josh Brolin — the star of 'Dune' and the Marvel Cinematic Universe films. The cast also includes Elizabeth Shue, John Ortiz, Jane Levy, and Emily Rudd. The creators paid special attention to making the events on screen look convincing. According to Brian Duffield, during the preparation of the film, the team consulted with whale specialists. Although for the sake of spectacle the authors had to allow for some artistic liberties, they tried to convey the details of the unusual situation as accurately as possible. A significant portion of the action takes place inside the whale, so the film is built on the feeling of confined space, lack of air, and a constant countdown of time. The new trailer emphasizes the hero's attempts to escape from the deadly trap.
